Description

Cross-reference of related applications

  This application claims priority from US Provisional Application No. 62 / 161,422 filed May 14, 2015, the contents of which are incorporated herein by reference in their entirety.

  Embodiments of the present disclosure relate generally to wireless communications, and more particularly to determining transmission parameters in a wireless network.

Explanation of related technology

  In a wireless network, a network element may indicate transmission parameters used by the network element to the mobile terminal by control signaling or other suitable methods. For example, in the current Long Term Evolution (LTE) system, during unicast transmission, the evolved Node B (eNB) applies a modulation code to a scheduled user equipment (User Equipment: UE). The modulation scheme (Modulation and Coding Scheme: MCS) is indicated by Downlink Control Information (DCI). Transmission parameters may include a modulation and coding scheme, resource allocation, packet size, and so on. The mobile terminal can thereby receive information transmitted according to these transmission parameters from the network element. The network element may set the same or different transmission parameters for each packet.

  Depending on the type of wireless communication such as LTE machine type communication (MTC), the eNB may use one or more (up to six) physical units when transmitting a physical downlink sharing channel (PDSCH). A resource block (Physical Resource Block: PRB) pair is assigned to a specific 1.4 MHz region in the first subframe, and PDSCH is repeated in a number of subsequent subframes. Also for the UE of LTE MTC in the coverage enhanced (Coverage Enhanced: CE) mode, the eNB assigns a repetition level to the UE. Thereby, UE can grasp | ascertain the repetition number in PDSCH transmission. At present, it is under consideration how to transmit this transmission parameter (ie, repetition level) to the UE in relation to other transmission setting information. Furthermore, when transmitting the repetition level to the UE, it may be necessary to reset another transmission parameter such as a transmission block size (TBS).

  Therefore, it is desirable to flexibly notify the UE of this transmission parameter (ie, repetition level) in relation to other transmission setting information so as to maximize system performance.

  For purposes of explanation, the following details are set forth in order to facilitate an understanding of the disclosed embodiments. However, it will be apparent to those skilled in the art that these embodiments can be practiced without specific details or may be practiced with equivalent constructions.

  FIG. 1 shows a wireless system according to an embodiment. The description of this embodiment and other embodiments described later is developed mainly in accordance with an LTE system for machine type communication (MTC). However, those skilled in the art will appreciate that the present disclosure is not limited thereto. In fact, the various aspects of the present disclosure are useful in any wireless network that benefits from the determination of transmission parameters as described herein. Examples of such a network include CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and the like. The terms “network” and “system” are often used interchangeably. The CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA1000. UTRA includes WCDMA (registered trademark) and other variants of CDMA. CDMA1000 covers IS-1000, IS-95, and IS-856 standards. A CDMA network may implement a radio technology such as GSM. OFDMA networks include Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, A wireless technology such as an ad hoc network may be realized.

  As shown in FIG. 1, the radio system includes a network element 200 such as an eNB and a plurality of UEs (mobile terminals) such as LTE MTC UEs. Unlike the mobile terminal, the network element 200 indicates a functional element on the network side. For example, the network element 200 may include an eNB. Solid lines with double-headed arrows indicate ideal downlink and uplink transmissions between the mobile terminal and the network element. It is well known that a wireless mobile system includes a network of each wireless cell implemented by a transmitting station known as a cell site or base station. A wireless network provides a wireless communication service to a plurality of transceivers (often mobile). A network in which network elements cooperate with each other can realize a wireless service that is wider than the wireless coverage provided by a single network element. Each network element is connected to another network (often a wired network (not shown)). The other network has a further controller responsible for resource management and possibly connection to another network system (such as the Internet) or a Metropolitan Area Network (MAN).

  In this specification, the terms “user equipment” and “mobile terminal” are treated as being synonymous, and mobile phones, smartphones, computers (including desktops, laptops, etc.), other mobile devices or terminals (LTE MTC UE, MTC) Including, but not limited to, devices, handheld computers, personal digital assistants (PDAs), video cameras, set top boxes, personal media devices, etc.), or any combination thereof. The term “radio” refers to any radio signal, data, communication, or but not limited to 4G (eg, LTE, LTE-A), Wi-Fi, Bluetooth®, 3G (eg, 3GPP, 3GPP2, UMTS). ), HSDPA / HSUPA, TDMA, CDMA (eg, IS-95A, WCDMA (registered trademark)), FHSS, DSSS, GSM (registered trademark), PAN / 802.15, WiMAX (802.16), 802.20, Narrowband / FDMA, OFDM, PCS / DCS, analog mobile communication system, CDPD, satellite system, millimeter or microwave system, acoustic, other interfaces including infrared (ie IrDA).

  3GPP (3rd Generation Partnership Project) is a Rel. 3 for further LTE physical layer improvement for MTC. 13 (Release 13) specification was newly formulated. Rel. The 13 specification MTC UE needs to support only 1.4 MHz (that is, only six PRB pairs) as an RF band in any of the system bands and in both the downlink and the uplink. Rel. The research purpose of 13 MTC is to standardize a technique for extending the FDD coverage by 15 dB when an MTC device is placed at a disadvantageous position, for example, deep in a building. Examples of the technology include subframe bundling technology based on hybrid automatic repeat request (HARQ) for physical data channels, and enhanced physical downlink control channel (PDCCH) based on inter-subframe scheduling with repetition. Resource allocation using), but is not limited thereto. The coverage expansion amount should be set for each cell and / or for each UE and / or for each channel and / or for each channel group. Rel. The research objective of 13MTC also includes providing a power reduction scheme in both normal and extended coverage to achieve ultra-long battery life.

［表２］

In the current LTE system for unicast transmission, the eNB indicates the MCS index to the scheduled UE in DCI. As shown in Table 1, LTE TS36.213, which is incorporated herein by reference, defines a total of 32 MCS entries. From this table, one MCS index is selected according to the channel quality confirmed by the UE. In the table, one column is a column of “TBS index”, which indicates a TBS index of an MCS index allocated for a specific resource allocation. Table 2 based on LTE TS 36.213 shows the TBS for each MCS index and each resource allocation (6 PRB pairs or less resource allocation). That is, when the eNB assigns an MCS index and resource allocation in scheduling DCI, the TBS is determined accordingly. The eNB does not need to indicate the TBS in scheduling DCI.
[Table 1]

[Table 2]

  As described above, for LTE MTC UEs in coverage extension (CE) mode, the eNB identifies one or more (up to 6) PRB pairs in the first subframe of PDSCH transmission during PDSCH transmission. The PDSCH is repeated in a number of subsequent subframes. The eNB also assigns a repetition level to the UE. Thereby, UE can grasp | ascertain the repetition number in PDSCH transmission. In the current standard, the eNB does not need to notify the scheduled UE of the TBS. The TBS is clearly determined by the assigned MCS index and the assigned physical resources. However, in the CE mode UE, data transmission may be repeated in the time domain, so the total resource amount is determined by the allocated resources and the total number of repetitions in each repetition subframe. Therefore, it is not appropriate to determine the TBS by the conventional method. Furthermore, RAN1 is currently examining how to notify the mobile terminal of transmission parameters (ie, repetition levels) in association with other transmission setting information.

  In order to solve the above problem, the present application provides three approaches 1 to 3. Hereinafter, for the purpose of explanation and illustration, Method 1 and Method 2 will be described using a new TBS table and repetition number table. Further, Method 3 will be described with a repetition number table. However, these tables can be represented in other suitable data formats and / or data structures and / or data sets. Therefore, the present application is not limited to this expression.

In this table, there may be many repetition level set indexes and repetition level indexes. The repeat level index may indicate 1, 2, 3, or any other suitable repeat level. The repetition level set index indicates the number of repetitions corresponding to each repetition level. That is, this table may be defined by two-dimensional elements that can define the number of repetitions more flexibly. Table 3 shows an example of the repetition number table.

The set of {R21, R22, R23} corresponds to the number of repetitions for

The set of {R31, R32, R33} corresponds to the number of repetitions for

Corresponds to the number of repetitions for.

  For example, in Method 1 according to an embodiment, a repetition level set index and a repetition level index may be set for the eNB and signaled to the UE. This may be realized by a broadcast signal, UE designated RRC signaling or physical layer signaling. When the repetition level set index and the repetition level index are acquired, the UE can grasp the number of repetitions of transmission such as PDSCH according to Table 3.

  For example, it is assumed that the eNB sets the repetition level set index 2 and the repetition level index 3 and signals to the UE. Then, from Table 3, the UE can recognize that the number of repetitions is R23. In practice, which TBS index to set may be determined according to the implementation, such as the UE traffic type.

  Technique 1 further uses a new TBS table defined by the repetition level set index, resource allocation, and transmission block size index. The new TBS table may be used by the UE to obtain a TBS for data transmission when the eNB repeatedly notifies the UE of the level set index, resource allocation, and transmission block size index.

  In the present embodiment, in each TBS auxiliary table as described above, even if a certain resource allocation has the same repetition level between a lower TBS and a higher TBS, resources are not wasted greatly. Absent. This is because the lower TBS has a lower coding gain than the higher TBS.

  In another embodiment, the transmission block size index is not repeated. This is Method 2. Method 2 also uses a new TBS table defined by repetition level set index, resource allocation, and transmission block size index. The TBS table of Method 2 is the same as that of Method 1, except that the transmission block size index is not repeated in the TBS table of Method 2.

  This TBS table may be used for the UE to obtain a TBS for data transmission when the eNB notifies the UE of the resource allocation and the transmission block size index. Viewed another way, the UE may be used repeatedly to infer the level set index, as described in more detail below.

In the table,

Is the same as Table 4 of Method 1. Similar to Table 4 of Method 1, one repetition level set index may correspond to two or more transmission block size indexes. However, in Method 2, each of the repetition level set indexes does not overlap with each other. Corresponding to each set of For example, in Table 4 of Method 1, all

May correspond to the same transmission block size index set such as {0, 1, 2, 3, 4, 5, 6, 7}. On the other hand, in Table 8 of Method 2,

Corresponds to a transmission block size index set such as {8, 9, 10, 11, 12, 13, 14, 15}, and these sets may not overlap each other. Thereby, as will be described in more detail below, the repetition level set index can be estimated by the second transmission block size index set.

For example, in the example of Table 8, the eNB is

Get the repeat level set index like In this embodiment, when the eNB further notifies the UE of the repetition level index, the UE may determine the number of repetitions based at least in part on the repetition level set index and the repetition level index, eg, according to Table 3.

のような送信ブロックサイズインデックスをＵＥに通知したとする。その場合、ＵＥは例えば表８を参照してＴ６６０のような送信ブロックサイズを決定してもよい。 In one embodiment, the eNB notifies the UE of the resource allocation and transmission block size index, and the UE may determine the transmission block size based at least in part on the resource allocation and transmission block size index, eg, according to Table 8. As an example, eNB

Assume that the UE is notified of a transmission block size index such as In that case, the UE may determine a transmission block size such as T660 with reference to Table 8, for example.

  In technique 2, for a given resource assignment, the TBS of the iteration level set index may be in ascending order, or in other suitable orders in other embodiments.

  Next, method 3 will be described. Similar to Method 1 and Method 2 described above, Table 3 may be used in Method 3 to determine the number of iterations.

  In addition, technique 3 may use multiple MCS levels, each index corresponding to each repetition level set index. Further, the MCS level index may indicate other information such as a code rate and a modulation order such as QPSK.

  In one embodiment, the iterative level set index is determined based at least in part on the modulation and coding scheme level index. For example, when the eNB transmits a modulation and coding scheme level index to the UE, the UE may determine the repetition level set index based on a mapping between the modulation and coding scheme level index and the repetition level set index. Further, the mapping of the MCS level index to the repeated level set index may be determined in advance.

In the table,

For TBS.

  In one embodiment, the transmission block size is determined based at least in part on the third resource allocation and the transmission block size index. For example, when the eNB transmits the resource allocation and the third transmission block size index to the UE, the UE can determine the transmission block size with reference to Table 9 according to the resource allocation and the transmission block size index, for example.

  In one embodiment, each repetition level index as shown in Table 3 corresponds to each of the transmission block size ranges that do not overlap each other. For example, assume that there are three repetition level indexes. In that case, repetition level index 1 corresponds to a value in the range from minimum TBS = 16 to maximum TBS 328, repetition level index 2 corresponds to a value in the range from minimum TBS = 329 to maximum TBS 600, and repetition level index 3 corresponds to the minimum TBS. It may correspond to a value ranging from = 601 to the maximum TBS1032. In this case, the transmission block size ranges of the repetition level indexes 1 to 3 do not overlap each other.

  According to one embodiment, the repetition level index is determined based at least in part on the transmission block size and each transmission block size range. As described above, each repetition level index may correspond to each of the TBS ranges that do not overlap each other. Therefore, the UE that has acquired the TBS can identify the TBS range in which the TBS is included by comparing the TBS with each TBS range. After obtaining this information, the repetition level index corresponding to the specified TBS range can be determined.

  According to one embodiment, in technique 3, the number of iterations may be determined based at least in part on the iteration level set index and the iteration level index. For example, when the UE obtains the repetition level set index and the repetition level index, the number of repetitions can be determined with reference to, for example, Table 3 based at least in part on the repetition level set index and the repetition level index.

  According to various embodiments, the number of various parameters such as the above-described values and / or value ranges and / or modulation and coding scheme level index, resource allocation, transmission block size table index, repetition level set index, repetition level index, etc. It is an example. Thus, other embodiments may utilize other suitable values and / or value ranges and / or quantities, respectively. That is, the present disclosure is not limited to the above.

The determination may be based at least in part on the level set index, the first resource allocation, and the first transmission block size index.

  In one embodiment, the transmission configuration information includes a first parameter set, and the transmission frequency of the first repetition level set index and the first repetition level index is the first resource allocation and the first transmission block size index. Less than the transmission frequency. For example, the network element 200 may have the same number of consecutive times for several consecutive packets and use a different TBS for each packet. That is, TBS = 16 for packet 1, TBS = 32 for packet 2, and so on. The network element 200 transmits a first repetition level set index and a first repetition level index for several consecutive packets, and each first resource allocation and each first transmission block size index is several You may transmit with respect to each of a continuous packet.

  According to various embodiments, the larger transmission block size is for transmitting larger packets and the smaller transmission block size is for transmitting smaller packets. For example, when the eNB transmits 2064-bit information to the UE, the eNB may select TBS = 1032. Larger TBS is advantageous for transmitting large packets. This is because a packet can be completely transmitted with a small number of scheduling. This leads to lower control overhead, shorter packet transmission times and associated low power consumption. As another example, if the eNB sends 32-bit information to the UE, the eNB may select TBS = 32. A smaller TBS is advantageous for transmission of small packets. This is because there is no need to add padding bits for packet transmission, which reduces the number of repetitions and further reduces power. Compared with the existing method, the selection range of TBS is wide in this application. Thus, network elements can provide more flexibility. That is, the network element can set a more appropriate TBS to maximize system and / or network performance.

  According to various embodiments, a network element can transmit transmission configuration information via at least one of a broadcast signal, user equipment specified radio resource control signaling, and physical layer signaling. For example, the network element can transmit the transmission setting information included in the DCI.

  As shown in FIG. 3, the process includes step 302. In this step, the mobile terminal 100 receives transmission setting information used by the network element to determine transmission parameters. The transmission setting information includes a first parameter set, a second parameter set, or a third parameter set. The first parameter set includes at least a first repetition level set index, a first repetition level index, a first resource allocation, and a first transmission block size index. The second parameter set includes at least a second repetition level index, a second resource allocation, and a second transmission block size index.

That is, TBS = 16 for packet 1, TBS = 32 for packet 2, and so on. Subsequently, the network element 200 transmits a first repetition level set index and a first repetition level index for several consecutive packets, each first resource allocation and each first transmission block size index. May be sent for each of several consecutive packets. Here, the reception frequency of the first repetition level set index and the first repetition level index is equal to or less than the reception frequency of the first resource allocation and the first transmission block size index.
